Afghans are now Sweden's largest asylum seeking group, having surpassed Somalis. And most are children sent here by themselves. Between January and October this year, 3,300 Afghans sought refuge in Sweden. The figures represent a 74 percent increase compared with the same time period last year, reports TT.

The news agency writes that an "exceptional proportion" of the cases are children who arrive in Sweden alone, but does not give a figure.

"The primary cause is the deteriorating security situation in Afghanistan," says Anders Rydén at the Migration Authority to TT.
